Can the same rider take different sizes on these two bikes?

Yes. Frame labels are not standardized, so the same rider may need different sizes. This comparison deliberately avoids a generic matched-size answer and hands your measurements to Bike Fit instead.

Which has the taller front end: Cervélo Áspero or Wilier Rave SLR ID2?

Across matched sizes the Cervélo Áspero and Wilier Rave SLR ID2 front ends are within a few millimetres of each other, so posture will depend more on cockpit setup than on the frame.
